| 1 | A Design of 2-Stage Voltage Ramp-Up SRAM Physical Unclonable Function显示文摘Silicon physical unclonable function(PUF)implemented by static random access memory(SRAM)exists inherent demerit of unstable cells due to noise of environment and circuits,which significantly restricts its reproducibility.In this paper,a 16T SRAM cell with reset-delay circuit and a 2-stage voltage ramp up is fabricated and reported.Compared to conventional SRAM structure,each PUF cell adds a pair of pull-up PMOS(P-channel metal oxide semiconductor)and pull-down NMOS(N-channel metal oxide semiconductor)controlled by reset and delayed-reset signals respectively,resulting in two positive feedback stages with different amplification coefficients when the voltage is ramped up.PUF array consists of 4064 cells,322 dummy cells and a group of 8 series-connected inverters with an area of 304μm×650μm to match the digital post-processing module.PUF test chip was fabricated in HHGrace 110 nm platform with total area 1140×1140μm^(2).The average HDintra(intra-chip Hamming distance,also bit error rate,BER)and HDinter(inter-chip Hamming distance)values of the 50 PUF chips in SOP16 package measured at normal point(1.5 V/25℃)were 1.92%and 49.85%,respectively. | Minte SONG Nan LIU Shuaiyang ZHOU Zhengguang WANG Zhanqiang RU Peng DING Wei HUANG Helun SONG | 2024 | Chinese Journal of Electronics2024，33，2： | 0 |
| 2 | Orientational Separation of Sulfur in Petroleum Coke by Alkali Calcining and Reflux Washing显示文摘The application of high-sulfur petroleum coke after desulfurization in aluminum electrolysis anodes is an important development trend. However, removing sulfur from high-sulfur petroleum coke is still a significant challenge.This study proposes alkali calcining and reflux washing to examine the impacts of temperature, particle size, the mass ratio of Na_(2)CO_(3) to NaOH, and total sodium addition on the desulfurization efficiency and mechanism. The results show that the desulfurization rate increases with increasing temperature, increasing total sodium content, and decreasing particle size. The addition of alkali can significantly reduce the opening-ring reaction temperature of thiophene and convert organic sulfur into inorganic sulfur(Na_(2)S). Three washing methods were compared, and reflux washing was selected to separate inorganic sulfur(Na_(2)S) from calcined petroleum coke. The sulfur content in petroleum coke decreased from 7.29% to 1.90%, with a desulfurization rate of 80.13% under optimal conditions. The petroleum coke was analyzed before and after desulfurization using X-Ray diffraction(XRD), Scanning Electron Microscopy(SEM), Infrared Spectroscopy(IR), Thermogravimetric Analysis and Differential Scanning Calorimetry(TG-DSC), Gaschromatography-mass Spectrometry(GC-MS). The results show that thiophene and benzothiophene in petroleum coke are decomposed and converted into octane and ethyl cyclohexane. These new observations are expected to provide further understanding and guidance for the utilization of highsulfur petroleum coke. | Su Song Li Minting Ye Fu Wei Chang Li Xingbin Deng Zhigan | 2023 | China Petroleum Processing & Petrochemical Technology2023，25，4： | 0 |
